Aren't some encryption support only available in PK-ZIP?

PKZIP claims to support X.509 certificate sign/encrypt support, and I
don't recall seeing that in Info-zip.

I would recommend use of TAR + GZ or possibly TAR + BZ2 instead.  If
signing/encryption of data is required, use OpenPGP or S/MIME (PKCS#7).
